IP network information database in mobile devices for use with media independent information server

a technology of mobile devices and information servers, applied in the field of wireless networking, can solve the problems of generating unnecessary signaling burden, mobile devices will unnecessarily send miis queries and repeatedly receive the same superfluous information, and routing protocols cannot be properly delivered packets, etc., to achieve optimal and efficient mobile device miis query and response communication, facilitate the fetching of only delta information, and reduce superfluous traffic

Abstract

A mobile device receives wireless network information from a MIIS (Media Independent Information Server), and builds its own database of existing networks with their associated characteristics, appropriately mapped with GPS (Global Positioning Satellite) coordinates or other appropriate form of geographical location identifying information. Consequently, the mobile device becomes “smart” over time through the learning process of first attempting to utilize its own developed database and, only if such database information falls short, making a remote query to a MIIS to get required information for session continuity and performing handovers. The mobile device may store the information received from the MIIS in its own local database together with a time-stamp. Each time the mobile device needs to get updated or new information, it sends a request to the MIIS along with the time-stamp appended to the request. In this way, the mobile device is sent only the information that it does not already have stored in its database.

Description

BACKGROUND

[0001] 1. Field of the Invention

[0002] The present application relates generally to wireless networking, and more particularly to systems and methods for supporting the seamless handoff or transfer of mobile devices across different network access points of homogeneous or heterogeneous wireless networks, whereby such mobile devices may connect to different wireless networks and / or wireless network access points as needed to maintain session continuity.

[0003] 2. General Background Discussion

[0004] Internet Protocol

[0005] IP is a connectionless protocol. The connection between end points during a communication is not continuous. When a user sends or receives data or messages, the data or messages are divided into components known as packets. Every packet is treated as an independent unit of data.

[0006] In order to standardize the transmission between points over the Internet or the like networks, an OSI (Open Systems Interconnection) model was established. The OSI mode...
